Which of the following is NOT a component of Newton’s first law of motion? a
An object at rest stays at rest.
b
An object in motion stays in motion.
c
An object in motion has a constant velocity (speed and direction) unless acted on by a balanced force
d
An object in motion has a constant velocity (speed and direction) unless acted on by an unbalanced force.

C.) is the correct option !!

An object in motion has a constant velocity (speed and direction) unless acted on by a balanced force.

because a balanced force can't cause change in it's velocity.

just go with your heart buddy

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
